Cards.py is a Python class library that implements two classes, playing_card and card_deck. The card_deck class acts like a standard Python list object that contains playing_card objects and has several built-in convenience methods like deal() and shuffle().

CashCow is a library for clearing Internet payment transactions with the Danish PBS through an SSL connection, provided by the OpenSSL library. CashCow will clear Dankort, Visa/Dankort, Eurocard, Mastercard, and Visa transactions between a customer and PBS.

Cavalry is a Just-In-Time translator (compiler) for java bytecodes. It is written in Java and produces IA-32 Machine code. It depends on an IA-32 Assembler also written in Java and included in this package. The assembler uses an Intel / NASM type syntax and currently only produces raw machine code (no object formats eg ELF are supported). It currently only supports a limited number of instructions, bascially everything the Translator needs. The assembler can compile a source-file from the command prompt, but it is not very friendly at the moment.

CBE is a revision control system with integrated make-like functions written in pure Java. It can be used in a way similar to CVS but offers some new features like renaming files (while still keeping the history) and using a database as backend (optional).

Cbrowser is a very feature-laden front end to the popular source code indexing and querying program cscope. It is also designed to work with the free alternative to cscope called cs. It provides a source code browser and function call tree hierarchy.

ccaudio2 is a simple, highly portable,
stand-alone, C++-based framework for manipulation
of audio data. Its goal is to be a C++ framework
that is as useful as "audiofile" or "sndfile" is
for C programming, and to cover various generic
and useful manipulations of audio data as well as
audio file access. A stand-alone audio processing
command line tool is also provided to demonstrate
library functionality. ccaudio2 compiles under Mac
OS X, POSIX systems, and Win32 systems.

CCCC (C and C++ Code Counter) is a simple command line tool which parses files in the supported languages and builds a set of reports in HTML of numeric measurements (metrics) on those files. Metrics are divided into three groups. Procedural metrics include lines of code, lines of comment and McCabe's cyclomatic complexity. Metrics of OO design (proposed by Chidamber and Kemerer) include depth of inheritance tree, number of children, coupling between objects, and weighted methods per class. Structural metrics (based on the work of Henry and Kafura), include fan-in, fan-out and information flow.
